lvchange -p now corrects in-kernel permissions on a logical volume
If a logical volume is read-only and active but its metadata states that it should be writeable (a situation that can arise if the configuration setting activation/read_only_volume_list is changed), you can now use the "lvchange --permission rw" command to bring the active copy in line with the metadata and make it writeable. Executing an "lvchange --refresh" command can do this as well, but this new feature might be more convenient in some circumstances. The opposite is also true: The "lvchange --permission r" command will now refresh an active logical volume that should be read-only. For information on the lvchange command, see the lvchange(8) man page.
